Methanol → Methyl 5-chloro-2-fluoro-4-((3-(hydroxymethyl)-adamantan-1-yl)methoxy)benzoate

A solution of 5-chloro-2-fluoro-4-((3-(hydroxymethyl)adamantan-1-yl)methoxy)benzoic acid (3.53 g, 9.57 mmol), 4-dimethylaminopyridine (0.23 g, 1.90 mmol), and methanol (3.87 mL, 95.70 mmol) in anhydrous dimethylformamide (50 mL) under nitrogen was treated with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (3.67 g, 19.10 mmol). The reaction mixture was stirred for 24 hours at ambient temperature; diluted with ethyl acetate (200 mL) and washed with water (100 mL), saturated ammonium chloride (100 mL), and brine (100 mL); dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (3:1 hexanes:ethyl acetate) to provide the title compound (0.65 g, 18%): 1H NMR (300 MHz, CDCl3) δ 7.90 (d, J=7.9 Hz, 1H), 6.59 (d, J=12.6 Hz, 1H), 3.85 (s, 3H), 3.56 (s, 2H), 3.23 (s, 2H), 2.11 (br s, 1H), 1.74-1.40 (m, 14H); MS (ES+) m/z 383.1, 385.1 (M+1).
